HI I'm Victor Pinto, AR programmer. I worked with Unity3D and Vuforia SDK since 2013. I know very well Vuforia features. In my previous developments I've used ImageTargets (image recognition), VideoPlayback (AR Videos), CloudRecognition (more than 1000 images - internet required), UsedDefineTargets, VirtualButtons, Framemakers and other extern pluggins.
I can add content to the app without update it in the stores using Unity3D.
I have Unity pro licence.
And building this Unity project for Android and iOS. Don't afraid to talk me for more details. Greetings!
